Google is on the roll when it comes to its browser, having stamped out five stable releases this year alone. The latest stable version of Chrome 8 includes a built-in PDF viewer, better sync options, and support for the upcoming web apps.

Chrome’s hidden settings can be accessed by typing in about:flags into the address bar.

According to NetApplications, Chrome’s web usage share is on the rise, having crossed the 9.27 percent mark in November and making Chrome the third most-popular browser in use.

If you’re on the developer or beta channel, you’ll need to switch to the stable channel before you install this version of Chrome. Those of you already on the stable channel should see Chrome update itself automatically.

If not, hit the Wrench menu, choose About Google Chrome and hit the Update Now button. Alternatively, you can download stable Chrome 8 release for Mac OS X, Windows, and Linux here.
